11 Dec 1944British destroyer HMS Cassandra (Cdr. P.F. Powlett, DSO and Bar, DSC, RN) was hit by a Gnat torpedo fired by German U-boat U-365. The entire bow ahead of the forward magazine, including 'A' gun turret were blown off and the structure abaft this to the forward bulkhead of the fuel tanks was wrecked. Cassandra was taken in tow (stern first) by the British frigate HMS Bahamas (T/A/Lt.Cdr. W.S. Thomson, RNR). Later the tow was passed over to a Soviet tug which towed her to the Kola Inlet. 62 men lost their lives in this attack.
